.In the accompanying drawing jthe numeral 10 denotes 'a fdooru frame; and 11' a ,door pivotally mounted therein to close the ment between saidlugs. It is provided with tumbler slots; which tumblers 26 j are slidablylocated, each tumbler having a pin 27 projecting through the pin openings in" lthefresetting plate and through the "door where they are accessible lat the front of 1 the door for the purpose of operating the tumblers to pl-ace; thein'i in position to permit movement Of-Lill e bolt throwing plate; Each tumbler; is "provided-with fa locking stud 128 tumbler plate and: between the lugs 15 ,;hav'- j j v j 100 soarranged v that-itmaylcontrol the move- I 5o opening therethrough. bolt l2' ismountedv "in, any -suitable*marmer:(upon the back oi v the'door to engagearecess or keeper 13in the door frame asgherein; shown" this "bolt ing a sliding movement [crosswise of the "door betwee'n said lugs. A spring -30qis properly engaged with the bolt throwing plate' tomov'e'it'backwardly, and this plate has {lbfliilg-JnOllIjltGd inloops 14 fastenedgtoo the ii 9, 15" 2' ll w l 3;] 31 f 1a finger" 31 U positioned to engage a finger 3210 1 the bolt 12 for the purpose of mov ing the latter, spring being interposd between a. projection ,from,the bolt throw ing plate and the ,boltto' move" the ilatterl into its keeper recess, as shown, this spring thrusting againstthe finger 32 on the bolt V v The parts are so constructed that eachuofr the locking studs upon, the tumblers be arranged to registeryvith a releasing r ecess M in the bolt throiving plate, 'ivherby any one or more of the tumblers may be;

moved to register 'itsjlocking stud with a releasing recess.

In use the iparts 'W ill'be' .sov arranged that theloclring'studs' on a1 vnumber of the -tumblers will normally regis- 5 ter with their cooperatingreleasing recesses; these tumblers, When the parts larle "so arranged, are termed as deadtumblers. 1

Theparts willwbe-so arranged that the re- *mainder of the t'umblers must be -moved- :to

cause their studs toyregister With the releasingwrecesses, and when so arranged th'ese tumblers are termed llve tumblers. From this uconstruction it Will be seen that they -,liive" tumblers must be moved to enable the lock to be operated, but idf a dead tu'mbler'be moved it will so position its "stud that thelock cannot be operated. For the l "purpose of description the tumblers a, Z2," '0, d, and e are shoW-n herein as liv tumblers andare the ones'to bemoved to enable the lock to be operatedu order to enable each ofthe tumblers to act as a dead or live tumbler it is necessary that the location of the releasing l recesses and the studs may be changed one With respect to another, and I have provided means in my improved lock whereby thischa'nge may be readily made in a simple manner and-Without requiring the :lock to 1 be ta ken apa-rt. In effecting this result the bolt throwing plate is provided with a number of locking stud recesses Within which thefstuds may move when the tumblers are moved lengthwise of the door; and thereleasing recesses 34 in the plates '36 carried by'the plate 29 open out of these locking stud recesses; releasingrecess plate 36 1s zremova'bly lnserted -1n-a-releas1ng recess "plate opening "3.7 appurtenant to each of the either end of its cooperating locking stud recess, and as a ready means forjremoving and arranging the releas ng recess plates a threaded openlng 38 1s formed-in each plate "Within hich a threaded stud may be 'removably: secured for the purpose of removthe plate;

In he" "peration'of the device ,the tumblers 'a, "b, c;*d;*an'd e are first moved to cause their locking studs to register With there leasing recesses; i *soonas the last" stud is moved intolregistering position with? its recess the spring i30ziiavill= gmove :thebolt throwing plate 29 backward'ljthe ifirigers 31' and .32 engagin gtoimove the bolt '12 from engagement 1 withi' looking the :dooriv As thei door isazswun'gf.
